The detail customization for the vertex delta model. This basically just adds the properties specific to the vertex delta model to the trainings settings. But as we inherit from the FMLDeformerGeomCacheModelDetails class, it directly creates all the other properties for us as well, and inserts error messages when something is wrong, creates some groups, etc.
